About Our Hospital

Ace Animal Hospital | Fremont Speciality & Emergency Vet

  • My pets have had wonderful care from Dr. Longley. She was willing to explain all the options and costs in detail. She cared for my 20-year-old cat who developed kidney disease, as well as my cat Rocky and dog Eddie, who has back trouble. The vets are patient, positive, and willing to work with you to have the best care possible. I highly recommend them! The techs and office staff have been great too.
    - Barbara B.
  • It is a pleasure every time I come to Ace animal hospital. The staff is very welcoming and knowledgeable. They make sure everything is good for you. I would recommend this animal hospital to anyone.

  • I took my dog here for an allergic reaction to fleas. They were very thorough. I was grateful the vet spent so much time talking with me about all of my dog's issues, my concerns, the options, as well as discussing cost with me before doing anything.
    - Megan S.
